These are actually two commits, but these are small changes on ~same place
so I put them into one DR.
First change is in Dockerfile - it removes unnecessary argument from package installation.
Second change is in set_openid script - it used sed and it hadn't escaped variable properly,
so I had to change it to AWK.
Third change is in config file - it sets httpsonly to 0, so we could use it locally via http
(to overcome problems with self-signed certificate).
